Not gotten away from God?????

I have some concerns about a friend of mine, who is a Christian, & she has become sexually active with a couple people over the last few months. First was intimate with a guy then they broke up, then she was intimate with another guy, which she found out later that he had lied about his marital status & was actually MARRIED.....and now she's back with the first guy and being intimate with him again. She's very recently divorced, & had stated to me when we first met a little over a year ago, that she & I were very similar. In the midst of having conversations with her recently, she made the comment that she has not gotten away from God, she's just having a problem with this 'one thing'. I am trying so hard not to be judmental, & preachy, & self-righteous, etc. It's difficult, though, but I try & remember that God is the one to be the judge, & not me. I should not try to play God. But is it possible to continue down this path knowingly, and still have an intimate relationship with God? I'm just a little confused & trying to make sense out it. Not to mention the fact that it has definitely stirred things up for me, such as I guess I feel like this has 'threatened' my own sense of values & beliefs, I do believe what the Bible says about sex out of marriage. And this is something I have struggled with now with a particular person in my life for about a year, who doesn't necessarily believe in God, but I have managed to avoid the temptation, & have managed to be pretty strong about it & stick to my beliefs, with the help of God, & I try to recognize that it is the devil that puts thoughts into my head, like it's okay, everybody does it, it's no big deal, etc etc etc. At any rate, since I have been pretty close friends with this lady for a little over a year, & she has chosen to go down this path now, it has been more difficult for me to stick to my values & beliefs, & am questioning them a great deal now, as I really did respect this friend of mine. I'm also fully aware that I am solely responsible for my actions regardless of what anybody else is doing. Any thoughts & suggestions on this topic, of is this possible to maintain a relationship with God, but still be on the 'wrong path'? I hope this topic is allowed on here, I figured it would be because it definitely relates to Christianity and the Bible. Any feedback would be helpful.
